Changing Table Ownership

I have a *very* large database (~360 tables) which will be converted from 5.x to 7.x. In the interim, I would like to change the ownership of all tables in the database to a single user. DOes anyone know of a simpler way to do this besides doing a dbexport, vi'ing the file to substitute the new owner globally, and then dbimporting the whole darned thing?
